Seems that my GN engine has lower oil pressure recently...
Used to be:
Hot Idle = 15psi
Cold Idle (30F) = 90psi
Now:
Hot idle = 10psi
At 1950rpm on the highway = 20psi
Does GNttype.org state that it should be 37psi at 2500rpm?
If so, seems mine is a bit low. What could change in the engine to lower the oil pressure?
Is it recommended to run thicker oils to raise the pressure?
The car seems to run good still.
Thanks,
